一般现在时的用法

一、概述

一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性，它不表示特定时间内发生的事。 二、一般现在时的结构

时态的结构指的是动词的变化形式。一般现在时间有两种结构，一种是动词原形，用于主语为不是第三人称时的情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。1.We often get up early in the morning.

2.My father often gets up early in the morning. 三、谈谈“主语为第三人称单数，其后动词s添法”

在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。其后动词s添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, China, my book,等等 3.He sometimes goes to school by bike.

4.My father works in the hospital as a doctor. 四、动词第三人称单数变化规则

动词第三人称变化的规则与可数名词复数变化的规则相同。 规则一、一般在词尾加-s。

如：looks, puts. reads, sees, skis等。 规则二、以-o, -s, -x, -sh, -ch结尾的加-es。

如：goes, does, misses, passes, mixes, fixes, pushes, wishes, watches, teaches,等。

规则三、以辅音字母加y结尾的，变y为i，再加-es。注意一定是辅音字母加y才变，若是元音字母加y，则直接加-s。

如：fly → flies, try → tries, fry → fries, copy → copies

buy → buys, enjoy → enjoys, play → plays, say → says, pay → pays五、一一般现在时的句子转换

（1）当句子中有be动词或情态动词时，则把be动词（am, is , are）或情态动词(can,could、may,.shall,.will,would等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例： ①陈述句：She is a student. 一般疑问句→ Is she a student? 否定句→ She is not a student. ②陈述句：I can swim.

一般疑问句→ Can you swim? 否定句→ I can not swim.

（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成一般疑问句；在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。例： ①陈述句：We get up at 7:00 every morning.一般疑问句→Do you get up at 7:00 every morning?否定句→We don’t get up at 7:00 every morning. ②陈述句：She has a little brother.

一般疑问句→ Does she have a little brother?否定句→ She doesn’t have a little brother. 六、练习巩固
